To all whom tt may concern: f

Be .it known that I, CoLcoRD UPToN, a citizen of the United States, and resident of Baltimore city and State of Maryland, haveinvented certain new and useful Improvements in Antifriction-Bearings', of which the following is a specification.

My invention relates to improvements in the type of anti-friction bearings comprising inner' and outer concentric faces or members and rolling members therebetween, and the object of my invention is to provide a simple and eilicient bearing which shall be cheap to manufacture, capable of ready assembling of parts, and durable in use.

My invention comprises inner and outer concentric races or members, the inner race being provided with a peripheral groove or raceway adapted to receive working rollers or rolling members and annular bearing surfaces at the sides of said Y roove, and radially disposed retaining anges without said surfaces, working rollers within said groove between the races, separator rolls between the working rollers and bearing upon said sidesurfaces between said radial flanges, and a retainer in ring-like form provided with openings receiving the working rollers and adapted to fit over the separator rolls to retain them upon the inner race, the

outer race having a bearing surface to -receive said working rollers.

The separator rolls interposed between the working rollers keep the latter all properly spaced apart'at all times, and at least one of thel openings in the retainer is of such dimensions that one of its edges will Contact with the corresponding working roller projecting through such opening in either direction oi travel of the rollers aroundthe raceway to cause such roller to carry the retainer along with it, but the edges other openings in the retainer are larger than such iirst-named opening sovthat the of said o-peningswill'not contact with the corresponding rollers projecting through such openings, whereby t-he retainer is not required to aline the working rollers or keep them in alinement, but is merely used to restrain radial movement of the separator rdetail face view rolls, by which means friction between the working rollers and the retainer is materially reduced. While I have referred to one of the openings in the retainer being relatively small with res )ect to the other openings in the retainer or the purpose stated, it will be understood that two or more of such openings diametrically or symmetrically disposed around the races may be suiciently small to contact with the corresponding working rollers while the other openings are suflicientlydarge not to contact at their edges with the corresponding rollers, and thereby to balance the weight of the retainer. i

Reference is to be had to the accompanying drawings forming part hereof, where-l Fig. 5 is a view corresponding to Fig. 3, adapted as a cone-type bearing, Fig. 6 is a view similar to Fig. 2 of the cone-type bearing. Figs. 7 and 8 are sectional views illustratingidilerent forms of openings in the retainer, and Fig. 9 is a face View illustrating the retainer according to Fig. 7.

y In the drawings the numerals l, 2, indicate respectively inner and outer concentric races or members, suitably spaced apart to receive between them the `Working rollers or rolling members 3. The vided A with a peripheral l groove or raceway la, shown providedA with outwardly inclined or beveled edge i portions 1*? and with peripheral wearing faces-1c on opposite sides of the beveled portions l", and with the opposed radially disposed flanges or walls l" outside of the surfaces l". Rollers 3 are shown provided-with beveled ends 3, the circular portions of said rollers fitting the groove 1El and the beveled parts 3l of the vrollers fitting the beveled faces 1b, the rollers also bearing against the wearing surface 2SL of the outer race l2, t-he latter having the beveled surface 2b adjacent .one end.

.in anti-friction hearing co rising spaced,concentric-race rings haviiig) races,

",the inner race ring having a peripheral tainer is of such dimensions as to contaetI i ring also having annular wearing-surfaces with the corresponding working roller prof jecting through the saine so that in either g direction of travel of the working rollers around the raeesytlie retainer l. b v the above named roller, will be carried around with the i'ollei's,b|1t other openings Lll' of the re tainer are inadelarger in the direction of the cireiin'iference of the retainer thanA said opening l? so that the working rollers yprojet-itingtherethrough will not be in contact with the transverse edges ol said openings. but are held spaced'therefron'i b v the retainer'rolls, and vtl'ierebigv the retainer not required to aline the working rollers or keep A.hem in alineim-nn but restrains the radial movement ot' the separator rolls, friction bei ween rthe working rollers and the retainer being thereb \v materially rediieed. rlfhile one ot the openings 4 may be of the size statedy it will be understood that.,dianietrieall v opposed openingsl may be so arranged while the other r'ipenings l" are larger, as shown in Vig. T, or'three ot' such openings 4 spaced at 120" apart ma)7 be ot' the size ,stated and the other openings l" oi' a larger sixt-as illustrate/l in hier. whereby the wt-igltttof the `retainer is balanced.

`ln assembling the .parts the separator rolls 5 are placed upon the inner race 1, the retainer l is sl pped overthe saine, the working rollers Il are then passcdthrotigh the openingsl l". l" of. the retainer between the adjacent pairs'wof separator rolls 5,. and then 'the outer raf-e is slipped over such assembled parts. i i f ln 5 and tithe construction is similar to thatV abovedescribed, excepting that the wearing surfaces 1a and f2 arent an angle to or taperedwith respect tothe axis ot' the rares l, the. retainer t being corre pondinglv shaped whereby a cone-type bearing provided. 1
